HW 10.1, 10.2 Score: 34.22/38 25/27 answered Question 19 Test the claim that /1 is different than /42. A random sample of size 30 yields 1 = 19.64 and a random sample of size 34 yields x2 = 18.9. Use o = 0.10, and assume that o = 1.1 for both populations. 1. The population distribution requirement for this test is: O None since n1 and n2 2 30 O None since this is a Z-test O Need a normally distributed population since this is a T-test O Need a normally distributed population since nj and n2 P2 O Ho: p1 2 p2; Ha : p1 /2 2. This is a O two right left tailed test and the distribution used is O T since both o values are not known O Z since testing two proportions O Z since both o values are knownThe Degrees of Freedom are "'3?- 3o '33:? WA; this is a Z-test C- 29 3. The STS (round to 3 decimals} is: The P-value {round to 4 decimals} is: 4. The decision at a = 0.10 is: 17' Do not reject Ho since P 3' a: '31:? Reject Ho since P g a '33:? Do not reject Ho since P > a: '3' Reject Ho since P :3 a The conclusion is: '3' There is insufficient evidence to reject the claim that #1 is different than p12 {:33 There is sufficient evidence to reject the claim that ,u1 is different than #2 '33:? There is insufficient evidence to support the claim that [.111 is different than #2 '33:? There is sufficient evidence to support the claim that p11 is different than [.112
